摘要:

介绍了等离子喷涂制备固体氧化物燃料电池（SOFC）中的电解质、阴阳极及其功能组件的研究进展,分析了其中的关键技术.研究表明：采用等离子喷涂,通过选择适当的粉末原料,工艺优化和改进送粉方式,可以得到满足SOFC要求的致密电解质,多孔阴极和阳极.三者的厚度均为30～50 μm,SOFC总厚度低于100～120μm,可以将固体氧化物燃料电池的运行温度降低到中温800℃下的范围,降低电池运行温度,从而降低了对相关材料的要求和运行成本.

Abstract:

The current progress of electrolyte, cathode, anode and their sub-assemblies of SOFC fabricated by plasma were overviewed and the key manufacturing techniques for SOFC were also analyzed in this article. The research showed that dense electrolyte, porous cathode and anode could be manufactured using plasma spray with optimized technique and proper powder delivery and powder starting materials. The thickness of three SOFC functional units all distributed 30~50 mm, and the total thickness of SOFC was within 100~120 mm, which lowered the operation temperature to 800 ℃ and reduced the requirement for related materials of SOFC and operation cost.

Key words: plasma spray solid oxide fuel cell(SOFC)
